The rotating shaft and support transmission device comprises a support, a fixedly connected piece and a rotating shaft transmission part, and the working principle is as follows: when the shaft core is positively rotated, the shaft core drives the driving wheel to positively rotate, and the driving wheel drives the driven block of the cam through the driving block, so that the cam is positively rotated. After the driving block positively rotates to drive the driven block to positively rotate by a first angle (such as 70 degrees or 80 degrees) and two convex blocks on the butted surface of the cam and the concave wheel are staggered, namely plane contact interference between the concave wheel and the cam is converted into transitional slope surface interference, at the moment, the first elastic piece stores energy and releases, so that the concave wheel is driven to axially slide to drive the cam to continuously positively rotate by a second angle (such as 110 degrees or 100 degrees) to enable the driven block to be separated from the driving block; at this time, the arc gap on the shaft core is just opposite to the through hole on the concave wheel, the second elastic piece stores energy and releases the locking piece to be pressed into the arc gap, the concave wheel is axially locked by the locking piece, the cam is circumferentially locked, that is to say, after the first angle, the bracket is sprung out and is locked after the second angle is sprung out, damping (transitional slope surface interference between the concave wheel and the cam) is carried out in the spring-out process so as to control the spring-out speed, thus, the bracket and the rotating part (host part) on the fixedly connected shaft core are not linked, the bracket and the fixedly connected piece are locked together, the rotating part (host part) on the fixedly connected shaft core can independently and freely rotate relative to the bracket and the fixedly connected piece, the rotating part (main machine part) on the fixedly connected shaft core can stay at will within a set angle under the torque force provided by the torque force component. When the rotating component (main machine part) on the fixedly connected shaft core rotates reversely after rotating positively, the shaft core rotates reversely, the shaft core drives the driving wheel to rotate reversely, the driving wheel cannot rotate reversely through the driven block of the driving wheel driving cam at first because the driving block of the driving wheel and the driven block of the cam are separated, but when the driving wheel rotates reversely by a third angle (such as 100 degrees or 110 degrees) and the like, the driving wheel can rotate reversely through the driven block of the driving wheel driving cam, the locking piece rotates in the arc-shaped notch on the shaft core because of the rotation of the shaft core, at the moment, the locking piece is separated from the arc-shaped notch, namely the locking piece is pressed into the through hole again, and store energy to the second elastic component, thus, the axial locking of the concave wheel is unlocked, the concave wheel can slide in the axial direction, at this moment, the driving wheel drives the cam to rotate reversely, the cam rotates reversely, the concave wheel is driven to slide axially, and then the first elastic component is stored energy again, that is, the locking of the bracket A is opened after the rotating part (the main machine part) on the fixedly connected shaft core rotates reversely by a certain angle, and the bracket A rotates by a certain angle after the rotating part (the main machine part) on the fixedly connected shaft core is closed downwards after the bracket A is locked and opened.

According to the working principle, an electronic device (such as a two-in-one computer) applying the rotating shaft and the bracket transmission device can realize the following functions: when pushing the host, the bracket is driven to open, for example, before 80 degrees of opening, the bracket is started along with the host, and no action is generated. When the host is opened by 85 degrees+/-5 degrees, triggering the support to spring and lock, wherein damping is provided in the spring opening process to control the spring opening speed, after that, the support is not linked with the host, the host can rotate independently, and the host can stay at any angle of 0-180 degrees; the main machine is manually closed, and when the main machine is closed for a certain angle, the support is locked and opened, and after the support is locked and opened; when the host is folded downwards for a certain angle, the bracket can rotate with the host for a certain angle. After the bracket rotates a certain angle, the bracket can be conveniently closed manually.
